Charminick

Hey everyone so I am having a hard time deciding what starter to choose. I was leaning towards pikachu mainly because of the extra side story. But I am unsure if it is worth it espically cause I heard you can catch a wild Pikachu early in the game in Viridan forest. I was also considering Squirtle because he is one of my all time favorites and charmander see cause I really want Charizsrs. Any suggestions???
